专用信息传输平台的组网方案和分层路由协议设计
|
摘要
随着无线自组网研究的不断成熟,无线Mesh网络以其网状的拓扑结构和对自组网路由技术的借鉴,正逐步发挥其优势。无线Mesh网络是一个动态的自组织、自配置网络,可以很方便地提供健壮的、可靠的网络覆盖,其应用十分广泛。
本文的研究是基于专用军事信息传输平台的特殊应用场景,设计符合特定拓扑要求的组网方案,并研究可以最大限度提高性能的路由协议。所述目标系统,即专用信息传输平台,是一个全系统的数话网络,节点之间有很密切的上下级指挥和被指挥关系,对抗毁顽存性能有特殊要求,并且要求使用树形逻辑拓扑。本文提出了使用分簇式Mesh方式组网,同时采用先应式协议和反应式协议结合的分层路由协议,即簇内采用反应式路由协议,簇间采用先应式路由协议,以达到提高路由协议效率和网络抗毁性能的目的。
本文研究中使用NS2网络仿真工具对设计方案进行了仿真验证。结果表明,目标系统的丢包率、时延和网络开销均比单纯的先应式路由协议DSDV协议有所改善。在通信对数增大的情况下,由于网络拥塞程度增加,此种组网和路由策略的性能改善将更为显著,同时也解决了传统反应式AODV路由协议无限制泛洪的缺点,大幅度减少了路由开销,有很高的实际应用价值。
With the rapid development of mobile networks, Wireless Mesh Networks, due to its mesh topology and some technologies borrowed from mobile Network, is gradually playing a more important role in network organization. The application of wireless mesh network is quiteextensive,it is a dynamic self-organized, self-configurationnetwork, which can easily provide strong and reliable network coverage.
The study in this paper is based on a special information transmission platform, the aim is to design a networking scheme which corresponds with this logical topology, and to research on a routing protocol which can improve its performance at its utmost. The target system, which is called information transmission platform, is a whole digital system that onenode is subordinate to another and they have close relationships with each other, it has a great demand onanti-destroying ability and tree topology. As to its strict requirements for invulnerability and tree-like topology, a hierarchical clustering way of network organization is put forward, and a routing protocol that combines table-driven routing protocol with on-demand routing protocol is adopted to improve the efficiency and whole networking functioning.
The study in this paper uses NS2to verify the theory above. The Simulation results reveal that the packet loss rate,end-to-end delay and routing overhead of the target system are better than simple table-driven protocol. While the communication couples increase, the network traffic become worse, then this protocol can work better. Besides, the scheme solves the unlimited flooding disadvantage of on-demand protocol AODV and reduced the routing overhead to the largest extent. So it is worth studying in practical application.
